The Shademaker Sola Parasol is designed as a residential parasol so we would not recommend it for use in a school. I would suggest looking at the Shademaker Liberty Parasol instead.

I have given the price for the Shademaker Liberty 3.5m and the 4.0m, and also for the inground base,. You will not need the inground base if you can bolt the spigot base (which comes with the parasol) to a concrete or solid ground. I have attached some images and the product manual for you to look through. The "spigot base" that comes with the parasol is shown on page 4. When you move school you can just unbolt the spigot base and take it with you. Here is a summary of the product details:

• Marine-grade materials guarantee longevity.
• Anodized aluminum means no rust, no paint to flake, no timber to break.
• Large sizes provide maximum shade and space for multiple tables or seating areas.
• Unique, "fool-proof" rotational locking mechanism, canopy easy to raise and lower.
• Rotates 360°...follow the sun and shade a large area with only one parasol!
• Vented canopy facilitates airflow and provides greater stablity in wind.
• Light weight (30 kg) but extremely robust, can handle moderate to strong winds.
• Design features enable ease of installation and maintenance.
• Only one person needed for assembly and removal for seasonal storage.
• Designed for simple removal of entire canopy structure when not in use.

Let me know if you need more information
